Flowering plants evolved from gymnosperms like ginkgoes and conifers, which bear naked seeds. Unlike conifers, however, flowering plants nourish their seeds with a tissue called endosperm, which ...

They found that it has two sets of chromosomes (diploid) — one from the mother, one from the father — whereas the endosperm of all other angiosperms have three sets of chromosomes ...

The origin of flowering plants, or angiosperms, stands as one of evolutionary biology's great enigmas. Scientists know that they diverged from the seed-bearing plants, or gymnosperms, at least 150 ...

Growth of the maize (Zea mays) endosperm is tightly regulated by maternal zygotic and sporophytic genes, some of which are subject to a parent-of-origin effect. We report here a novel gene, maternally ...

The Sago palm, Cycas revoluta, of course, is not a palm at all, but a gymnosperm, and thus more closely related to pine trees than palms.The botanist in me wants to remind you that gymnosperms are ...
